DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] Referring to Figs. 1 to 3, the hinge assembly of the present invention comprises a hinge cup 10, an installation member 12, an arm 14 connected between the hinge cup 10 and the installation member 12, a damping device 16 connected to the hinge cup 10, a first resilient member 18 and a second resilient member 20 connected to the hinge cup 10, a first pin 22 connected to the arm 14 and the first resilient member 18, and a second pin 24 connected to the second resilient member 20. The first and second resilient members 18, 20 respectively provide a first force and a second force to the arm 14. The damping device 16 provides a damping force to the arm 14.

[0022] The hinge cup 10 comprises a first side wall 26a, a second side wall 26b, a bottom wall 28 which is connected between the first and second side walls 26a, 26b, a front wall 30 connected between two respective front ends of the first and second side walls 26a, 26b, and a rear wall 32 connected between two respective rear ends of the first and second side walls 26a, 26b. A receiving space 34 is defined by the first and second side walls 26a, 26b, the bottom wall 28, the front wall 30 and the rear wall 32. The first side wall 26a has a first hole 36a and a second hole 36b, and the second side wall 26b has a third hole 36c, a fourth hole 36d and a fifth hole 36e. The bottom wall 28 has a stop 38 located adjacent to the front wall 30, and the rear wall 32 has a positioning hole 40. The bottom wall 28 further has a first lug 42a, a second lug 42b and at least one or two first engaging parts 44. The first lug 42a has a first through hole 46a, and the second lug 42b has a second through hole 46b.

[0023] The installation member 12 is connected to the arm 14 and installed on a piece of furniture such as a cabinet.

[0024] The arm 14 is pivotably connected between the first and second side walls 26a, 26b of the hinge cup 10. The arm 14 is located adjacent to the front wall 30 of the hinge cup 10.

[0025] The damping device 16 is located in the receiving space 34 of the hinge cup 10 and comprises a damping member 48, a slide 50 and a housing 52. The damping member 48 has an engaging portion 54 on the rear end thereof, and the engaging portion 54 is engaged with the positioning hole 40 of the rear wall 32 as shown in Fig. 3. The damping member 48 has a piston rod 56 on the front end thereof, and the piston rod 56 is connected to the slide 50. Preferably, the slide 50 has a recess 58, and the stop 38 of the hinge cup 10 is engaged with the recess 58 to temporarily position the slide 50. The slide 50 has two wings 60 which are located corresponding to the first and second lugs 42a, 42b. Preferably, the two wings 60 are in contact with the first and second lugs 42a, 42b to temporarily position the slide 50. The housing 52 is located in the receiving space 34 and the damping member 48 is accommodated in the housing 52. The housing 52 covers the first and second resilient members 18, 20. The housing 52 has a room 62, an opening 64 communicating with the room 62, a positioning member 66, at least one or two second engaging parts 68, two slide slots 70 and two covers 72. The damping member 48 extends through the room 62 and the opening 64, and the engaging portion 54 extends through the opening 64. The bottom wall 28 of the hinge cup 10 has an installation hole 74 in which the positioning member 66 is inserted. The at least one second engaging part 68 is engaged with the at least one first engaging part 44 on the bottom wall 28 of the hinge cup 10. The slide slots 70 allow the wings 60 of the slide 50 to move linearly.

[0026] The first resilient member 18 is connected between the first lug 42a and the first side wall 26a. Preferably, the first resilient member 18 is a torsion spring pivotably connected to the first lug 42a and is covered by the cover 72 of the housing 52 as shown in Fig. 4.

[0027] The second resilient member 20 is connected between the second lug 42b and the second side wall 26b. Preferably, the second resilient member 20 is a torsion spring pivotably connected to the second lug 42b and is covered by the cover 72 of the housing 52 as shown in Fig. 4.

[0028] The first pin 22 is a U-shaped pin. Two ends of the first pin 22 extend through the first and second holes 36a, 36b and are located in the third hole 36c and the first through hole 46a respectively so as to be connected to the arm 14 and the first resilient member 18. The first resilient member 18 provides a first force to the arm 14.

[0029] The second pin 24 is a U-shaped pin. Two ends of the second pin 24 extend through the fourth and fifth holes 36d, 36e, one of the two ends of the second pin 24 extends through the second through hole 46b and is connected with the second resilient member 20. The second resilient member 20 provides a second force to the arm 14.

[0030] As shown in Fig. 4, the installation member 12 is installed to the cabinet 76, and the hinge cup 10 is connected to the door 78. When the door 78/arm 14 is moved toward a closed position relative to the cabinet 76/hinge cup 10 (shown in Figs. 5 and 6), the arm 14 pushes the slide 50 which moves the piston rod 56 to slowly retract into the damping member 48 to have a damping function. Therefore, the door 78 is slowly and quietly closed to the cabinet 76. In the meanwhile, the wings 60 of the slide 50 are separated from the first and second lugs 42a, 42b (Fig. 6 shows that one of the wings 60 is separated from the first lug 42a), and the stop 38 of the hinge cup 10 is moved away from the recess 58 of the slide 50.

[0031] As shown in Fig. 7, when the arm 14 is spread out relative to the hinge cup 10 at an open position, the piston rod 56 of the damping member 48 extends and moves the slide 50 until the wings 60 of the slide 50 contact the first and second lugs 42a, 42b (the drawing shows that one of the wings 60 contacts the first lug 42a). Simultaneously, the stop 38 of the hinge cup 10 is engaged with the recess 58 of the slide 50, so that the slide 50 is located at a position wherein the slide 50 can be pushed relative to the arm 14 to generate the damping function.

[0032] The damping device 16 is installed to the hinge cup 10 by the configuration that the engaging portion 54 of the damping member 48 extends through the opening 64 of the housing 52 and is engaged with the positioning hole 40 of the rear wall 32. Further, the at least one second engaging part 68 of the housing 52 is engaged with the first engaging part 44 on the bottom wall 28 of the hinge cup 10 so as to position the damping device 16 to the hinge cup 10. During the damping process, the wings 60 of the slide 50 are linearly movable in the slide slots 70 of the housing 52 so as to provide smooth and stable damping force. Accordingly, when the arm 14 contacts the slide 50 or when the arm 14 is closing toward the hinge cup 10, the damping device 16 provides stable damping travel.

[0033] It is noted that the travel distance of the damping device 16 can be adjustable. As shown in Figs. 8 and 9, in another embodiment, the hinge cup 10 has a guide groove 80. The guide groove 80 is located in the bottom wall 28 of the hinge cup 10 and substantially perpendicular to the rear wall 32 of the hinge cup 10. The housing 52 has a reception slot 82 which communicates with the room 62. The damping member 48 has a threaded portion 84, a guide portion 86 and an adjustment member 88. The threaded portion 84 is located corresponding to the positioning hole 40 of the rear wall 32 of the hinge cup 10. The threaded portion 84 of the damping member 48 partially extends through the positioning hole 40. The guide portion 86 extends through the guide groove 80, so that the damping member 48 is linearly movable relative to the hinge cup 10. The adjustment member 88 is located in the reception slot 82 of the housing 52 and is movably and threadedly connected to the threaded portion 84. The adjustment member 88 is partially exposed from the reception slot 82 of the housing 52. By this way, the damping member 48 is linearly movable linearly in the room 62.

[0034] As shown in Figs. 10 and 11, when the adjustment member 88 is rotated in a certain rotating direction, the damping member 48 moves to a first position relative to the hinge cup 10 in response to the rotation of the adjustment member 88, so that relative position of the slide 50 to the arm 14 can also be changed. Consequently, the impact angle, the arm 14 hits the slide 50 to generate the damping function when the arm 14 is pivoted to close the hinge cup 10, can be adjusted. The damping function is executed when the door 78 is located at the angle α relative to the cabinet 76 (as Fig. 10 shown), so that the door 78 is slowly and quietly closed within the range of the angle α. When the adjustment member 88 is further rotated in the certain rotating direction, the damping member 48 moves to a second position relative to the hinge cup 10 (as Fig. 11 shown), the arm 14 is pivoted toward the cabinet 76, the impact angle is changed from the angle α to angle β. Therefore, when the door 78 is being closed toward the cabinet 76 and the angle therebetween is within the range of the angle β, the damping function is executed so that the door 78 is slowly and quietly closed within the range of the angle β.

[0035] As shown in Fig. 12, the damping function 16 is shut off when the adjustment member 88 is rotated to move the damping member 48 to a third position relative to the hinge cup 10. Wherein, the slide 50 is moved away from the arm 14, so that when the arm 14 is located at the complete closed position relative to the hinge cup 10, the arm 14 does not touch the slide 50.

[0036] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
